Question: Since saturday i have had the feeling that i need to poop even after i have pooped. But it has also been very difficult to poop whenever i have tried to get it out. Over the paat month and a half i have been dealing with a respiratory infection that has been causing headache and lightheadedness. I have also had green poop for about the same amount of time as he respiratoryy infection. The poop in the toilet didnt look any different. It just appeared a shade of green on the toklet paper when i wiped. Yesterday i went to the doctor and recieved antibiotics for my respiratory infection. I recieved cefdinir. As of last night i just assumed that i had been constipated due to my diet. I had eaten fast food fried chicken and like 6-7 beers friday night, then i had a fast food burger and fries the next day. It is when i went home that i began feeling a wierd gassy feeling in my lower abdomin. Since then it has been difficult to poop and my poops have been small and stringy. Last night i assumed it was constipation and i took a laxative. I just pooped because of it and it was very diarrea-like and again it didnt appear a different color when i looked at it in the toilet, but when i wiped it was a yellowish color. Do you think that yellow color could be attributed to my antibiotics? My diet? Do i have a gluten allergy? Or do you think i have some sort of intestinal infection?
